MACHINE FOR COATING AND EMBOSSING MOLDINGS.

SPECIFICATION forming part of Letters Patent No. 407,847, dated July 30, 1889.

Application filed May 14, 1889. Serial No. 310,781. (No model.)

' citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Coating and Embossing Moldings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for coating moldings with a thin layer of composition and for embossing the same ready for gildin g,

. painting, or staining.

In the machines heretofore built for such purpose the guide-table and lower feed-roller were made stationary to be in a horizontal position. WVhen for coating and embossing angular moldings, an extra strip of wood of the length of the molding, shaped to form a bed for such molding, had to be provided to pass through the machine with each molding for supporting it on a horizontal line while passing under the embossing-roller, and it is the object of this my invention to pro duce a machine in which fiat or angular moldings can be thus coated and embossed without extra supporting-strips; and with that object in view my invention consists of the novel devices and combinations of devices hereinafter described and specifically c] aimed.

In the accompanying drawings, Figure 1 represents a side elevation, and Fig. 2 a front elevation, of the machine; Fig. 3, a transverse vertical section on line so a: in Fig. I, and Fig. at a longitudinal vertical section on line y y in Fig. 2. Fig. 5 is a plan of the feed-roller, scraper, and one of the two guide-tables; Fig. (3, an elevation of the adjustable guide-strip; and Fig. 7, an end elevation of one of the boxes of the embossing-roller shaft, showing the latch for locking said shaft laterally.

Corresponding reference characters in the several figures of the drawings designate like parts.

A Adenote two frames of equal pattern, connected bybrace-rods 1 and 2. In these frames and in bearings cast therein is journaled the feed-shaft B, and below this feed-shaft is j ournaled, also in bearings forming part of frames A A, the main driving -shaft C, having mounted tight and loose pulleys 3 and 4 for transmitting power by belt from the lineshafting. Spur wheels 5 and 6 are also mounted upon shaft C to be laterally shiftable, for bringing one or the other into gear, and thereby driving the machine at a slower or faster speed. This shaft 0 is held in lateral position by collars 7.

Upon shaft B is mounted a spherical collar 8, upon which is fitted the hub of a pulley D,

shaped in its bore like a spherical zone, so as to form a universal joint on such collar, and this pulley D is made longitudinally in halves bolted together, and in order that this pulley may rotate with shaft B the spherical collar 8 has a groove cut laterally around its circumference, and two pins 9, diametrically opposite, are fitted into radial sockets in the central web of the pulley, which pins 9, having square heads, are fitted into the circumferential groove of the spherical collar 8. This pulleyD thus mounted is carried by the shaft B, to rotate therewith, While laterally it has a free oscillating movement. This pulley D is guided to occupy a straight position or any angular position by a crank-shaft E, pivoted in suitable bearings in frames A A to occupy a longitudinal position central to pulley D on the same horizontal plane with shaft 13, with its semicircular crank portion extending around the bottom face of pulley D. V

Upon the crank portion of shaft E are secured to be rigid therewith two cross-heads '10 and 11, having trunnions at their transverse ends for rollers 12, that, bearing against the ends of the face of pulley D, guide the same to retain any desired angular position in which said shaft E maybe adjusted. This shaft E has rigidly secured thereto lever 13, provided with an eye for a bolt 14,.that is passed through a segmental slot of a crosspiece 15, secured against the front of the machine for turning said shaft E to the desired angle, and then securing it by tightening bolt 14:. Upon shaft E are also rigidly mounted V-shaped brackets 16, upon which are secured two tables F and F, one in front and the other one in rear of pulley D, and with their top faces in line with the top of the face of pulley D. These tables also swinging with the shaft E, they will occupy any angular position corresponding with the angular position on which pulley D is held by rollers 12.

Centrally above shaft B is another shaft G, pivoted in boxes 17, that are vertically guided in the upper extensions of frames AA, each such boX having secured thereto a screw 18, passed through eyes 19 and 20 of such frames and tapped through the hub of a miter-wheel 21, fitted between eyes 19 and 20, and both wheels 21 meshing with miter-pinions 22, mounted upon the ends of a shaft 23, journaled in semicircular brackets 24, that are sleeved upon brace-rods 2. Upon the middle of shaft 23 is mounted a hand-wheel 25, which by turning in one direction or another will raise or lower both boxes 17 uniformly. Upon this shaft G, between adjustable collars 26 and 27, is mounted the embossing-roller H, between which and the feed-pulley D the molding I to be coated with composition is passed.

For holding the molding inproper line for the feed-pulley D and embossing-roller H a guide-plate 28 is attached to the top of one or both tables F F, to be laterally adjustable thereon, the same being held parallel with the table by having a rib upon its bottom guided in a groove of such table and being secured in proper position by a thumb-screw 29. To the inner edge of this plate 28 is secured by hinges a strip 30, which may be held in any desired angular position relative to the table F or F by a plate 31, having a flange 011 its abutting edge, and being laterally adjustable by a thumb-screw 32, passed through a slot in plate 31 and tapped into plate 28. By shifting this plate 31 up to the jointed edge of plate 28 with strip 30 said strip 30 will be sustained in a rectangular position relative to the table F, while by adjusting this plate a greater or less distance from said edge the strip 30 will occupy a corresponding angular position suitable for the angular shape of the moldingItobe embossed. Between the arms of one of the brackets 16, that hold table F, is secured to the bottom of such table the scraperplate 33, that is to clean the pulley D of any composition adhering thereto, and in order that such composition may not be brought in contact with rollers 12 of cross-head 11 a V- shaped angleplate 34 is riveted upon such scraper-plate 33, which is provided with the flanges 35 for securing the plates to the bottom of the table F. V

The shaft B is driven from shaftO by either spur-wheel 5 of shaft 0 meshing with spurwheel 36 of shaft B, or, as shown in the drawings, by spur-wheel 6 of shaft 0 meshing with spur-wheel 37 of shaft B.

Upon one end of shaft Gis mounted a pin ion 38, driven from wheel 37 by two intermediate pinions 41 and 42, pivotally secured against a segmental plate 39, having a radial arm 40, that is pivoted upon shaft B, so as to swing 011 such shaft and to hold the pinion 41 in gear with wheel 37. The pinion 42 clears wheel 37 and meshes with pinions 41 and 38.

The segmental plate 39 is slotted in its lower end for adjustably securing it by a bolt 43, for moving the pinion 42 into proper engagement with pinion 38 again whenever the shaft G has been raised or lowered. By this device a positive motion is imparted to shaft G, which, correspondingly with the diameter for a relative uniform circumferential speed of pulleys D and embossing-wheel H, may be varied by interchanging the pinion 38 with a larger or smaller one.

The shaft G must be removable for interchanging the embossing-wheels H, and for this purpose it is provided with an annular groove 44, exterior of one of its journal boxes 17, to which is pivotally secured a semicircular latch 45, and thereby holds the shaft from lateral movement,while with raising the latch 45 and loosening the collars 26 and 27 the shaft G can be pulled out partly or entirely.

For operating this machine the composition for coating is rolled out into a thin strip of the required width, the end of such a strlp being attached to the end of the molding to be coated. It'is then guided by hand to cover such molding while passing through between Wheels D and H, where it is pressed onto the wooden surface of the molding and is embossed by roller 11.

This machine, as will be readily seen, is

very complete for embossing either fiat or angular moldings, its arrangement providing for v a rapid adjustment and its movements being easy and noiseless.

What I claim is 1. In a machine for the purpose described, the combination, with the vertically-adjust- .able shaft G, carrying the embossing-roller,

of shaft B, having mounted thereon spherical collar 8, pulley D, pivotally mounted upon such collar to rotate therewith, and radial pins 9, engaging a laterally-circumferential groove of collar 8, whereby such pulley can assume any angular position relative to shaft 13 while rotating therewith, as set forth.
